Abstract
Objective: To investigate the measurement of small airways by high-resolution CT and image post-processing software. Screen and analyze the reconstructed airway parameters in order to find the best imaging biomarker parameters of small airway changes and calculate the reference value range; meanwhile, explore its influencing factors. Methods: From a water plant and a medical school, 169 cases of the general population aged 20 to 60 were selected as research objects, and questionnaire surveys and CT tests were performed, and CT data were reconstructed with image post-processing software. The reference value range of the general population was evaluated, and a linear mixed effect model was used to adjust the age, gender, height, BMI, and smoking status, and analyze the influencing factors of airway parameters. Results: The ratio of sixth-grade tracheal wall area to total tracheal area in the Left B1+2 to carina was (53.01±13.35) %, Left B9 to carina was (50.44±12.98) %, Right B1 to carina was (52.73±12.22) %, and Right B9 to carina was (52.93±11.85) %. The ratio of nineth-grade tracheal wall area to total tracheal area in the Left B1+2 to carina was (44.08±14.66) %, Left B9 to carina was (42.44±15.89) %, Right B1 to carina was (46.51±14.03) %, and Right B9 to carina is (43.54±15.87) %. BMI affect the area of the tracheal wall, all p value<0.05. Conclusion: High-resolution CT small airway morphology can make a preliminary assessment of the susceptible population of small airway-related diseases based on a range of reference values, and prevent and control it in combination with influencing factors.

Abstract
OBJECTIVE To assess the effect of omega-3 polyunsaturated fatty acids (n-3 PUFA) on liver regeneration of rats with liver cirrhosis after hepatectomy and antifibrosis. MATERIALS AND METHODS Omega-3 polyunsaturated fatty acids were intravenously injected in n-3 PUFA group 3 days before the operation to 1 day after partial hepatectomy. 70% hepatectomy was performed in rats, which were subsequently divided into 4 groups, namely normal and hepatectomy group (PH); liver cirrhosis and hepatectomy group (LC+PH); liver cirrhosis, n-3 PUFA (1 mL/kg), and hepatectomy group (LC+n-3 PUFA+PH); liver cirrhosis, n-3 PUFA (2 mL/kg) and hepatectomy group (LC+n-3PUFA*+PH). Body/liver weight ratios, serum parameters, histopathological examination, immunostaining, inflammatory cytokine and quantification of mRNA expression were also investigated. RESULTS Liver regeneration was significantly delayed compared with PH group 7 days after hepatectomy (PH) in LC+PH group. Besides, liver regeneration of LC+n-3 PUFA*+PH group increased significantly compared with LC+PH group 7 days after PH. In LC+PH group, liver cirrhotic was significantly higher compared with LC+n-3 PUFA+PH group 7 days after PH. In the meantime, liver cirrhosis of LC+n-3 PUFA*+PH group was significantly reduced compared with LC+n-3 PUFA+PH group 7 days after PH. Anti-inflammatory cytokine IL-10 was increased and pro-inflammatory cytokine IL-6 was decreased in LC+n-3 PUFA*+PH group compared with LC+PH group. N-3 PUFA also suppressed increments in mRNA expression for transforming growth factor-β and up-regulated the expression of matrix metalloproteinase-9 and matrix metalloproteinase-1 in the liver. CONCLUSIONS The mentioned results clearly show that n-3 PUFA reduces liver fibrosis and promotes liver regeneration, even under cirrhotic conditions. This could be a potentially useful treatment for liver cirrhosis.

Abstract
Objective: To explore the application value of heparin binding protein (HBP) in the diagnosis of severe infection in patients with silicosis. Methods: A prospective study was conducted on 150 patients with silicosis in the pneumoconiosis department of the General Hospital of Xuzhou Mining Group from January 2017 to March 2018. Among them, 100 were severely infected with silicosis and 50 were non-infected with silicosis. 30 patients were selected in the same period of physical examination as the control group. HBP, C-reactive protein (CRP) , procalcitonin(PCT) , white blood cell count (WBC) , neutrophil percentage, and absolute neutrophil count(ANC) were detected in all participants. Using the receiver operating characteristic curve(ROC) to analyze the diagnostic value of indicator above in patients with different stages of severe silicosis infection. Results: Plasma HBP levels in patients with severely infected silicosis group[(50.39±35.64) ng/ml] were higher than those in the non-infected group[(10.71±1.47) ng/ml] and the control group[(9.24±1.83) ng/ml] (P<0.05) , and with the increase of silicosis stages, there is an increasing trend (P<0.05). The ROC curve showed that the AUC of HBP in the patients with severe silicosis in the first, second, and third stages were 0.932, 0.977, and 0.964, which were higher than those of WBC, CRP, and PCT. Correlation analysis showed that HBP was positively correlated with WBC, CRP and PCT (r=0.711, 0.359, 0.729, P<0.01). Conclusion: HBP has high diagnostic efficacy in the diagnosis of severe infections in patients with silicosis, which may become a clinical screening indicator for severe infections in patients with silicosis and an auxiliary examination indicator for the stage of silicosis patients.

Abstract
Objective: To evaluate the prognostic value of kinetic changes in minimal residual disease (MRD) status, as well as its relationship with risk stratification, therapeutic response and treatment in patients with newly-diagnosed multiple myeloma (MM) . Methods: A total of 135 patients with newly-diagnosed MM were screened, and 105 patients who achieved VGPR or more as the best responses were included into this study. The MRD status was determined by multiparameter flow cytometry (MFC) at multiple intervals after two cycles of treatment until clinical relapse, death, or last follow-up. The statistical methods included Kaplan-Meier analysis, Cox regression, etc. Results: ①In all 135 patients, 57.8% (78/135) patients achieved MRD negativity (MRD(-)) after treatment. In 105 patients who achieved VGPR and thus included in this study, the MRD(-) rate was 72.4% (76/105) , with a median interval of 3 months from starting treatment to achievement of MRD(-) status. ②The 2-year PFS rate of patients with MRD(-) status was significantly higher than that of MRD(+) status (62.2% vs 41.3%, P=0.001) , while MRD persistence (MRD(+)) was an independent factor for poor prognosis (multivariate analysis for PFS: P=0.044, HR=3.039, 95%CI 1.029-8.974) . ③Loss of MRD(-) status (i.e., MRD reappearance) showed inferior outcomes compared with MRD sustained negative ones, the PFS was 18 months versus not reach (P<0.001) and the OS was not reach for both (P=0.002) . ④The 2-year PFS and OS rates of patients with duration of MRD(-)status≥12 months were significantly higher than those of the control group (PFS: 77.7% vs 36.7%, P<0.001; OS: 96.4% vs 57.9%, P<0.001 respectively) . Duration of MRD(-) status was associated with a marked reduction in risk of relapse or death (univariate analysis for PFS: P<0.001, HR=0.865, 95%CI 0.815-0.918; for OS: P=0.001, HR=0.850, 95%CI 0.741-0.915 respectively) . ⑤Moreover, even in patients carrying high-risk cytogenetic abnormalities (CA) or ineligible for ASCT, MRD negativity remained its prognostic value to predict PFS (high-risk CA medianPFS: not reach vs 19 months, P=0.006; ineligible for ASCT medianPFS: not reach vs 25 months, P=0.052 respectively) . ⑥Last, treatment with the bortezomib-based regimens contributed to prolonged MRD(-) duration (median MRD(-) duratio: 25 months vs 10 months, P=0.034) . Conclusion: Our findings supported MRD(+) status as an independent poor prognostic factor in MM patients, which implicated that duration of MRD(-) status also played a significant role in evaluation of prognosis, while loss of MRD(-)status might serve as an early biomarker for relapse. Therefore, monitoring of MRD kinetics might more precisely predict prognosis, as well as guide treatment decision, especially for when to start retreatment in relapsed patients.

Abstract
Background:Early diagnosis of rheumatoid arthritis (RA) is hampered by suboptimal accuracy of currently available serological biomarkers. Metabolomics may reveal promising biomarker candidates associated with the biomolecular processes of RA. In this work, we applied a high-performance chemical isotope labeling (CIL) LC-MS technique for in-depth profiling of the amine/phenol-submetabolome in serum samples. To avoid false positives and obtain high-confidence biomarker candidates, we analyzed three independent sets of serum samples collected from RA patients and healthy controls to examine the common effects.Objectives:We aimed to identify a metabolite signature with consistently high accuracy for RA.Methods:Serum samples were taken from 3 RA cohorts, which comprised 50, 49, and 131 RA patients, respectively. Within each cohort, there were sex/age-matched healthy controls: 50 in Cohort 1, 50 in Cohort 2, and 100 in Cohort 3. Among these 446 subjects, 75% were females and the average age was 52.5 years. Amine/phenol-containing metabolites were labeled by12C-dansyl chloride to improve the LC-MS detection. For each cohort, a pooled sample was prepared and labeled by13C-dansyl group to serve as the reference sample for relative quantification. Then the individual samples and the pooled sample were mixed 1:1. Finally, an LC-QTOF-MS platform analyzed the mixtures and output the intensity ratios of12C/13C peak pairs.Results:1,149 amine/phenol-containing metabolites were commonly detected across the three sample sets. Among them, 134 were positively identified by our dansyl-labeling standard library, and 141 were matched to predicted retention times and mass values of dansyl-labeled human metabolites. Visualized by the partial least squares discriminant analysis (PLS-DA), the overall amine/phenol-submetabolome demonstrated clear and consistent differences between healthy controls and the RA groups, with cross-validation Q2 = 0.765, 0.745, 0.793, respectively. The selection of significant metabolites was conducted according to the fold change and false-discovery-rate-adjusted Welch’s t-test. Cohort 1 demonstrated 85 metabolites having higher concentrations in the RA samples than the controls, and 89 metabolites with lowered concentrations. The numbers of increased/decreased metabolites in Cohort 2 and 3 were 87/26 and 90/53, respectively. Importantly, there were 59 significantly discriminatory metabolites commonly found in the three data sets (49 increased and 9 decreased). We picked the top three with the highest univariate classification performance to form a biomarker panel. We implemented the linear support vector machine (SVM) to build the classifier and the receiver operating characteristic (ROC) analysis to measure the performance. The area-under-the-curve (AUC) values (95% confidence interval) were 1.000 (1.000-1.000), 0.992 (0.967-1.000) and 0.902 (0.858-0.945) for the three cohorts, respectively. The results revealed the importance of examining multiple sample sets and even in the worst case (Cohort 3), our biomarker candidates could differentiate RA at 82.5% sensitivity and 82.5% specificity. Particularly, in Cohort 3, there were 30 RA patients negative for anti-cyclic citrullinated peptide and rheumatoid factor, and our metabolite panel demonstrated consistently high performance for differentiating these specific subjects from healthy controls.Conclusion:Metabolites showing significant and consistent changes associated with RA have been identified with high discriminative power.Disclosure of Interests:Wei Han: None declared, Xiaohang Wang: None declared, Liang Li: None declared, Stephanie Wichuk: None declared, Edna Hutchings: None declared, Rana Dadashova: None declared, Joel Paschke: None declared, Walter P Maksymowych Grant/research support from: Received research and/or educational grants from Abbvie, Novartis, Pfizer, UCB, Consultant of: WPM is Chief Medical Officer of CARE Arthritis Limited, has received consultant/participated in advisory boards for Abbvie, Boehringer, Celgene, Eli-Lilly, Galapagos, Gilead, Janssen, Novartis, Pfizer, UCB, Speakers bureau: Received speaker fees from Abbvie, Janssen, Novartis, Pfizer, UCB.

Abstract
Background:Osteoarthritis (OA) is a degenerative disease associated with changes in the articular cartilage and bone, severely affecting patients’ mobility and quality of life. Multiple factors including mechanical stress, metabolic alteration and inflammatory mediators are involved in the complex pathogenesis of OA[1]. Interventions targeting these pathogenic factors may contribute to the treatment of OA. MiRNAs are single strand non-coding small RNAs, which are regulated in chondrogenesis and OA[2,3]. Recent studies demonstrated that miRNAs are involved in the regulation of NF-κB signaling pathway by different mechanisms[4]. These interactions suggest that NF-κB related miRNAs may be used as potential biomarkers and drug therapeutic targets in clinical treatment of OA. However, the relationship between miR-214-3p and NF-κB pathway remains poorly understood in OA.Objectives:This study aimed to test the expression and biological function of miR-214-3p in OA, and explore its mechanism in osteoarthritic chondrocytes.Methods:Articular primary chondrocytes were isolated from human cartilage samples, which were acquired from patients with end-stage knee OA at the time of total knee replacement surgery (n = 27), according to protocols approved by the Ethic Committee of Zhujiang Hospital. Real time PCR (RT-PCR) and in situ hybridization (ISH) were used to detect the expression of miR-214-3p in OA and non-OA cartilage tissues. Interference of miR-214-3p was conducted using inhibitor, while overexpression of miR-214-3p was performed with mimics. Metabolism of extracellular matrix was detected by RT-PCR, western blotting and immunofluorescence in vitro. Flow cytometry were conducted to determine cell apoptosis. A luciferase reporter assay, was used to evaluate the interaction between miR-214-3p and its downstream target. Human chondrocytes were cotransfected with miR-214-3p and the IKBKB-overexpressing plasmid to confirm the interaction between miR-214-3p and NF-ĸB pathway. For in vivo studies, experimental OA was induced in 12-week-old male C57BL/6J mice by destabilization of the medial meniscus (DMM) surgery with miR-214-3p agomir intra-articular (IA) injection (once weekly for 12 days) or by IA injection (once weekly for 12 days) of miR-214-3p antiagomir. Mice were sacrificed 10 weeks after the first IA injection, and subjected to histological analyses.Results:MiR-214-3p was significantly reduced in human OA cartilage. The decreased expression of miR-214-3p in the OA cartilage tissues was directly associated with excessive apoptosis and imbalance between anabolic and catabolic factors of ECM. Mechanistically, we determined that miR-214-3p directly targeted IKBKB/IKK-b and thereby suppressed the activation of NF-ĸB pathway. IKBKB overexpression attenuated the inhibitory effect of miR-214-3p on NF-ĸB pathway. Furthermore, inhibition of miR-214-3p in mice joints triggered spontaneous cartilage loss and OA development, while IA injection of miRNA-214-3p agomir alleviated OA in the DMM mouse model.Conclusion:Our results reveal an important role of miR-214-3p in OA progression. MiR-214-3p was down-regulated while IKBKB was upregulated in OA. MiR-214-3p inhibits the NF-kB signaling pathway and suppresses the progression of OA through targeting IKBKB. Thus, miR-214-3p maybe a therapeutic target for OA.References:[1]Glyn-Jones S, Palmer AJR, Agricola R, Price AJ, Vincent TL, Weinans H, Carr AJ:Osteoarthritis.The Lancet2015,386(9991):376-387.[2]Nugent M:MicroRNAs: exploring new horizons in osteoarthritis.Osteoarthritis and cartilage2016,24(4):573-580.[3]Vicente R, Noel D, Pers YM, Apparailly F, Jorgensen C:Deregulation and therapeutic potential of microRNAs in arthritic diseases.Nature reviews Rheumatology2016,12(4):211-220.[4]Xu B, Li YY, Ma J, Pei FX:Roles of microRNA and signaling pathway in osteoarthritis pathogenesis.Journal of Zhejiang University Science B2016,17(3):200-208.Disclosure of Interests:None declared

Abstract
OBJECTIVE To determine if qualitative and quantitative measures of prefemoral fat pad (PFP) and quadriceps fat pad (QFP) are associated with incident radiographic osteoarthritis (iROA) over 4 years in the Osteoarthritis Initiative (OAI) study. DESIGN Participants in this nested case-control study were selected from the OAI study with knees that had Kellgren Lawrence grades (KLG) of 0 or 1 at baseline. Case knees were defined by iROA (KLG≥ 2) over 4 years. Control knees without iROA were matched 1:1 with case knees. Magnetic resonance images (MRIs) were read at P0 (time of onset of iROA), P-1 (1 year prior to P0) and baseline, and used to assess PFP (i.e., prefemoral hyperintensity alteration, patellofemoral hyperintensity alteration, maximum axial area) and QFP (i.e., hyperintensity alteration, mass effect, maximum axial area). Conditional logistic regression analyses were performed to study the associations between PFP/QFP measures and iROA, after adjustment for covariates. RESULTS 354 case knees with iROA were matched to 354 control knees. 66.9% of the participants were female, with an average age of 60.1 years. PFP prefemoral hyperintensity alteration measured at three time points (OR [95%CI]: 1.46 [1.18-1.82], 1.50 [1.20-1.88], 1.52 [1.22-1.89] respectively), PFP maximum axial area (OR [95%CI]: 1.07 [1.01-1.14], 1.08 [1.01-1.15], 1.08 [1.02-1.15] respectively) and QFP hyperintensity alteration (OR [95%CI]: 1.59 [1.27-2.00], 1.44 [1.13-1.82], 1.38 [1.09-1.73] respectively) were significantly associated with iROA in multivariable conditional logistic analyses. QFP mass effect measured at BL and P-1 (OR [95%CI]: 1.42 [1.11-1.82], 1.33 [1.01-1.73] respectively) were significantly associated with iROA. CONCLUSIONS Qualitative and quantitative measures of PFP and QFP are associated with increased iROA over 4 years.

Abstract
Objective: To analyze the clinical features of ulcerative colitis associated colorectal cancer (UC-CRC). Methods: A total of 869 inpatients with Ulcerative Colitis (UC) in Peking Union Medical Hospital from January 1998 to January 2018 were continuously enrolled. Clinical data and the outcome of colorectal cancer (CRC) were collected via medical records and telephone follow-up. Chi-square test and logistic regression model were used to analyze the data. Results: There were 16 patients in 869 UC inpatients who were diagnosed with CRC during a period of 7 548 person years and the incidence rate of UC-CRC was 1.84%. Compared to UC inpatients without CRC, a longer course of disease (OR=1.087, 95% CI:1.046-1.129) , a lower usage rate of 5-Aminosalicylic Acid(5-ASA) (OR=0.218, 95% CI:0.052-0.915) and a higher incidence rate of intestinal stenosis (OR=16.533, 95% CI:3.824-71.478) were found in UC inpatients with CRC. Conclusions: A long disease course is a risk factor for UC patients developing CRC, while 5-ASA therapy can reduce the risk of suffering from CRC. For UC patients with intestinal stenosis, CRC should be warned for occurring.

Abstract
The prevalence of gestational diabetes mellitus (GDM) is estimated at 14% globally, and in some countries, such as Singapore, exceeds 20%. Both women and children exposed to GDM have an increased risk of later metabolic diseases, cardiovascular disease and other health issues. Beyond lifestyle changes and pharmaceutical intervention using existing type 2 diabetes medications for expecting women, there are limited treatment options for women with GDM; targeting better outcomes of potentially affected infants is unexplored. Numerous animal models have been generated for understanding of pathological processes of GDM development and for development of treatment strategies. These models, however, suffer from limited windows of opportunity to examine risk factors and potential intervention options. By combining short-term high-fat diet (HFD) feeding and low-dose streptozotocin (STZ) treatments before pregnancy, we have established a mouse model with marked transient gestation-specific hyperglycemia, which allows testing of nutritional and pharmacological interventions before, during and beyond pregnancy.

Abstract
OBJECTIVE To determine whether the morphology of proximal tibiofibular joint (PTFJ) is associated with increased risk of incident radiographic osteoarthritis (iROA) over 4 years in the OA Initiative (OAI) study. METHODS A nested matched case-control study design was used to select participants from OAI study. Case knees were defined as those with iROA. Control knees were matched one-to-one by sex, age and radiographic status with case knees. T2-weighted MR images were assessed at P0 (the visit when incident ROA was found on radiograph), P1 (1 year prior to P0) and at OAI baseline. The contacting area of PTFJ (S) and its projection areas onto the horizontal (load-bearing area, Sτ), sagittal (lateral stress-bolstering area, Sφ) and coronal plane (posterior stress-bolstering area, Sυ) were assessed, respectively. RESULTS 354 case knees and 354 matched control knees were included, with a mean age of 60 and a mean body mass index (BMI) of 28 kg/m2. Baseline PTFJ morphological parameters (S, Sτ and Sυ) were significantly associated with iROA over 4 years, and these associations remained unchanged after adjustment for BMI, number of knee bending activities, self-reported knee injury and surgery. S, Sτ and Sυ were also significantly associated with iROA at P1 and P0. In subgroup analysed, S, Sτ and Sυ were associated with risks of incident joint space narrowing in the medial, but not the lateral tibiofemoral compartment. CONCLUSION Greater contacting area, load-bearing area and posterior stress-bolstering area of PTFJ were associated with increased risks of iROA, largely in the medial tibiofemoral compartment.

Abstract
BACKGROUND AND PURPOSE Patient survival in high-grade glioma remains poor, despite the recent developments in cancer treatment. As new chemo-, targeted molecular, and immune therapies emerge and show promising results in clinical trials, image-based methods for early prediction of treatment response are needed. Deep learning models that incorporate radiomics features promise to extract information from brain MR imaging that correlates with response and prognosis. We report initial production of a combined deep learning and radiomics model to predict overall survival in a clinically heterogeneous cohort of patients with high-grade gliomas. MATERIALS AND METHODS Fifty patients with high-grade gliomas from our hospital and 128 patients with high-grade glioma from The Cancer Genome Atlas were included. For each patient, we calculated 348 hand-crafted radiomics features and 8192 deep features generated by a pretrained convolutional neural network. We then applied feature selection and Elastic Net-Cox modeling to differentiate patients into long- and short-term survivors. RESULTS In the 50 patients with high-grade gliomas from our institution, the combined feature analysis framework classified the patients into long- and short-term survivor groups with a log-rank test P value < .001. In the 128 patients from The Cancer Genome Atlas, the framework classified patients into long- and short-term survivors with a log-rank test P value of .014. For the mixed cohort of 50 patients from our institution and 58 patients from The Cancer Genome Atlas, it yielded a log-rank test P value of .035. CONCLUSIONS A deep learning model combining deep and radiomics features can dichotomize patients with high-grade gliomas into long- and short-term survivors.

Abstract
Objective: To explore the value of heparin-binding protein (HBP) in early diagnosis of severe infection in silicosis patients. Methods: From January 2017 to June 2018, fifty silicosis patients with severe infection and fity without infection were recruited in the Second Affiliated Hospital of Xuzhou Medical University. In the severe infection group, the time of patients diagnosed with severe infection was set as the reference point for time. Blood samples were selected from the hospital inspection system sample library at the time of 24, 48, and 72 hours prior to the reference point. In the non-infection group, blood samples were selected within 24 hours of admission. The blood samples were tested for the levels of HBP, C-reactive protein (CRP), procalcitonin (PCT), and white blood cell (WBC) count. The area under the curve (AUC) of the receiver operating characteristic (ROC) curve, sensitivity, specificity and Youden index (YI) were used to evaluate the diagnostic efficacy of each indicator. Results: The HBP levels at 72, 48, 24, and 0 hours before the diagnosis in the severe infection group were significantly higher than those in the non-infection group (all of the P values <0.001), and decreased with the prolonged time before diagnosis. The ROC curve showed that the AUC of HBP at 72, 48, 24, and 0 h before the diagnosis in the severe infection group [0.828 (0.750-0.907), 0.966 (0.920-0.998), 0.967 (0.961-0.998), 0.997 (0.994-0.999)] was higher than that of PCT [0.563 (0.450-0.677), 0.687 (0.581-0.794), 0.726 (0.622-0.829), 0.982 (0.973-0.986)] and CRP [0.564 (0.449-0.680), 0.648 (0.535-0.761), 0.705 (0.594-0.817), 0.963 (0.924-0.983)] and WBC [0.492 (0.377-0.607), 0.497 (0.383-0.612), 0.628 (0.519-0.738), 0.700 (0.598-0.802)] at the corresponding time. The sensitivity, specificity and YI of HBP were 88.9%-97.6%, 77.1%-98.4% and 0.66-0.96 at 72, 36, 24 and 0 h before diagnosis, respectively. Conclusion: Heparin-binding protein can be used for early diagnosis of severe infection in silicosis patients.

Abstract
We report a new diluted ferromagnetic semiconductor Li1+y(Cd,Mn)P, wherein carrier is doped via excess Li while spin is doped by isovalence substitution of Mn2+ into Cd2+. The extended Cd 4d-orbitals lead to more itinerant characters of Li1+y(Cd,Mn)P than that of analogous Li1+y(Zn,Mn)P. A higher Curie temperature of 45 K than that for Li1+y(Zn,Mn)P is obtained in Li1+y(Cd,Mn)P polycrystalline samples by Arrott plot technique. The p-type carriers are determined by Hall effect measurements. The first principle calculations and X-ray diffraction measurements indicate that occupation of excess Li is at Cd sites rather than the interstitial site. Consequently holes are doped by excess Li substitution. More interestingly Li1+y(Cd,Mn)P shows a very low coercive field (<100 Oe) and giant negative magnetoresistance (~80%) in ferromagnetic state that will benefit potential spintronics applications.

Abstract
Objective: To determine the association of serum fibroblast growth factor-23 concentrations with age-related cardiac diastolic function subclinical state and whether this association differs by sex. Methods: Seven hundred sixteen healthy subjects (aged 35-89 years, 68.4% female) were selected from National Basic Research Program of China (973 Program-China Medical University subsection) between January 2014 and February 2015 and assigned into 4 groups according to sex and age:< 60 years old male and female group, ≥ 60 years old male and female group. Blood biochemical indicators and general clinical data of the subjects were measured. The glomerular filtration rate (eGFR) were estimated using the Modified Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI-ASIA) equation. The fibroblast factor 23 (FGF-23), C-reactive protein (CRP) and interleukin-6 (IL-6) were measured by enzyme-linked immunosorbent assay (ELISA). Cardiac structure and function parameters including left atrial diameter (LAD), inter-ventricular septum thickness (IVST), left ventricle posterior wall thickness (LVPWT), left ventricle mass index (LVMI),left atrial mass index (LAVI) and the ratio of peak velocity of early filling to the septal early peak diastolic mitral annulus velocity(E/e') were measured by echocardiography. Association between serum FGF-23 and aging-related diastolic function subclinical status was analyzed by binary Logistic regression analysis. Results: (1) Serum log-transformed FGF-23 levels were significantly higher in males than in females [(2.0±0.3) ng/L vs (1.9±0.4) ng/L, P<0.05]. (2) Cardiac diastolic function gradually decreased with age, and age related cardiac diastolic function decline of female was significantly higher than males[E/e':<60 years old male group (7.6±2.6), ≥ 60 years old male group (8.6±2.7), P<0.01;<60 years old female group (8.3±2.3), ≥ 60 years old female group (9.5±3.1), P<0.01; LAVI:<60 years old female group (14±5) ml/m(2), ≥ 60 years old female group (16±5) ml/m(2), P<0.01]. (3) Serum FGF-23 was significantly positively correlated with age (r=0.089, P<0.05) and LAVI (r=0.084, P<0.05) in total study population while with E/e' (r=0.149, P<0.05) only in males. There was no significant correlation between serum FGF-23 and cardiac diastolic function parameters in females. (4) Binary Logistic regression analysis showed that median and high FGF-23 were independently associated with age-related cardiac diastolic function decline (OR=2.831, 95% CI: 1.144-7.009, P=0.024; OR=2.548, 95% CI: 1.053-6.163, P=0.038) in males. Conclusions: Serum FGF-23 concentrations are associated with age-related cardiac diastolic function subclinical state in a healthy Chinese population. High levels of FGF-23 are independently associated with age-related cardiac diastolic function decline in males.

Abstract
Objective:This study was designed to distinguish vestibular migraine(VM) from Meniere's disease(MD) by comparing age, sex, family history, audiological and vestibular test results in patients with VM or MD. Method:Forty-six patients with suspected VM, 60 patients with confirmed VM, and 60 patients with confirmed MD were studied. All patients were asked for detailed medical history, and then underwent bithermal caloric test and audiological test. The hearing function and vestibular function were analyzed. Result:①General conditions: the sex ratio with suspected VM, confirmed VM and confirmed MD was 1∶4.75, 1∶5.67 and 1∶1. Family history in these three groups was 80.43%(37/46),66.67%(40/60),6.67%(4/60), respectively. ②In the three groups, the abnormal rates of caloric test were 50.00% (23/46), 31.67% (19/60) and 78.33%(47/60), respectively.③The rate of pure tone audiometry abnormality in the three groups was 60.87% (28/46), 63.33% (38/60) and 100.00% (60/60), respectively. Of 46 suspected VM patients, 18 (39.13%) had high frequency hearing loss, 7 (15.22%) had full frequency hearing loss, and 3 (6.52%) had low frequency hearing loss. Among 60 confirmed VM patients, 18 (30.00%) had high frequency hearing loss, 15 (25.00%) had full frequency hearing loss, 4 (6.67%) had low frequency hearing loss, and 1 case (1.67%) with low frequency and high frequency hearing loss. Among 60 confirmed MD patients, 56 (93.33%) had full frequency hearing loss, and 4 (6.67%) had low frequency hearing loss. ④The difference of audiological test between patients with confirmed VM and patients with suspected VM was not statistically significant(P>0.05). The difference of bithermal caloric test between patients with confirmed VM and patients with suspected VM was not statistically significant(P>0.05).Compared with MD patients, the incidence of hearing loss and the incidence of abnormal bithermal caloric test in VM patients is lower(P<0.05). Conclusion:The abnormality rate of caloric test and the incidence of hearing loss in MD patients were higher than VM. The confirmed and suspected VM patients can be accompanied by hearing loss mainly with high hearing frequency decline. There was no difference in clinical characteristics between confirmed and suspected VM patients.

Abstract
To investigate the effects of different doses of soluble PD-L1 (soluble form of Programmed death ligand 1, sPD-L1) protein on Lewis lung cancer cells, flow cytometry was used to detect the expression of PD-L1 (Programmed death ligand 1) on the surface of Lewis lung cancer cell lines and the expression of PD-1 on the surface of T lymphocytes in peripheral blood and spleen cells of C57BL/6 mice. A Lewis lung cancer animal model of C57BL/6 mice was established by transplanting Lewis lung cancer cells subcutaneously. The sPD-L1 protein was injected into the abdominal cavity of the mouse (sPD-L1 Ig) (working dose: 2.5, 5, 10 μg per mouse), while the sPD-L1 control protein was injected as a control. The growth of Lewis lung cancer xenografts was observed. On the 18th day after tumor cell inoculation, T lymphocyte subsets in mouse spleen were determined by flow cytometry. The PD-1 molecules on the surface of Lewis lung cancer cell line, C57BL/6 mouse spleen T lymphocytes and peripheral blood T lymphocytes were positively expressed. Compared with the control group, the volume of the transplanted tumor of Lewis lung cancer in C57BL/6 mice was larger with 10 μg sPD-L1 I g injection (P less than 0.05), and no significant difference was observed in tumor volume with 2.5 μg and 5 μg injection (P > 0.05). A certain level of soluble PD-L1 (10 μg/ mouse) could promote the growth of transplanted tumors of Lewis lung cancer in C57BL/6 mice.

Abstract
OBJECTIVE To describe associations between presence of patellar tendon enthesis (PTE) abnormalities and symptoms, structural abnormalities, and total knee replacement (TKR) in older adult cohort. METHODS PTE abnormalities (presence of abnormal bone signal and/or bone erosion), were measured on T2-weighted magnetic resonance (MR) images at baseline in 961 community-dwelling older adults. Knee pain and function limitation were assessed using Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Bone marrow lesions (BMLs), cartilage volume and defects score, and infrapatellar fat pad (IPFP) area were measured using validated methods. Incidence of TKR was determined by data linkage. RESULTS Participants with abnormal PTE bone signal and/or erosion was 20%. Cross-sectionally, presence of PTE abnormalities was associated with greater pain intensity while going up and down stairs (β = 0.22 (95% confidence interval (CI); 0.03, 0.41)), greater risk of femoral BMLs (RR = 1.46 (1.12, 1.90)) and worse tibial cartilage defects score (RR = 1.70 (1.16, 2.47), and smaller IPFP area (β = -0.27 (-0.47, -0.06) cm2), after adjustment of confounders. Longitudinally, presence of baseline PTE abnormalities was associated with a deleterious increase in tibial BML size (RR = 1.52 (1.12, 2.05)) over 10.7 years but not symptoms, other structural changes, or TKR. CONCLUSION PTE abnormalities are common in older adults. Presence of cross-sectional but not longitudinal associations suggests they are commonly co-exist with other knee structural abnormalities but may not play a major role in symptom development or structural change, excepting tibial BMLs.
